Class WithLatestFrom

Namespace

Bonsai.Reactive

Assembly

Bonsai.Core.dll

Represents an operator that combines the latest values from the source sequences only when the first sequence produces an element.

The behavior of WithLatestFrom is very similar to CombineLatest, but while CombineLatest emits a combined value whenever any of the source sequences emits a value, WithLatestFrom only emits the combination when the first sequence emits a value (as long as the second sequence has emitted at least one value).

Examples

Use WithLatestFrom to combine two sources in time.

Video Synchronization

Use WithLatestFrom to combine two sources (e.g. frames from different cameras, or the closest frame to a key press).

Note

This example requires the Bonsai.Vision and Bonsai.Vision.Design packages to be installed.

Background Subtraction

Use WithLatestFrom to combine a source with a reference value for post-processing (e.g. background subtraction).

Note

This example requires the Bonsai.Vision and Bonsai.Vision.Design packages to be installed.

Alternative

Use CombineLatest to combine sequences if:

• You have more than two sources
• Need a higher-order operator
• Need to keep all the values from all the sources
